BELT-SHIFTER. A

SPECIFICATION forming part of Letters Patent No. 280,847, dated July 10, 1883.

Application filed February 2?., 1883. (No model.)

T0 all whom, it may concern/.-

Be it known that I, GEORGE H. Mo'rLEY, a citizen of the United States, residing at OX- ford, in the county of Oxford and State of Maine, have invented a new and useful Belt- Shifter, of which the following is a specification.

My invention relates to improvements in belt-Shifters, in which there is a table having a space in it for a belt attached to a cardingmachine, and on this table there is a smaller table in which is a space for the same purpose as that in the under table, the same belt passing through both spaces, each table having a space, corresponding with that in the tables, through the outer edge thereof, for the purpose of passing the belt therethrough, the space in the upper table being directly over that in the under table. The small table is held 'in position by two rods which pass through two grooves in the upper table. rlhe rods are fastened in posts in the under table. The table is moved backward and forward by means of a lever attached to a shaft of a cogwheel. The cog-wheel fits in a straight cog on the top edge of the small table, and the shaft of the cog-wheel fitsin two posts in the under table. In the under surface isa groove which ts in atrack in'the under table. When the shifter is placed in position and the belt on the carding-machine is passed through the spaces, it is ready for use. When it is desired to shift'the belt, the person moves the lever attached to the cog-wheel to the right or left, thereby forcing the belt off of one pulley of the carding-machine to another; and the objects of my invention are, first, to provide a power for shifting belts at a moments notice; second, that the belts may be shifted without being touched by the hands or feet of the person shifting them, thereby lessening the danger incident to shifting belts. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is the top sections of the entire machine. Fig. 2 is a top view of the machine as it appears after the removal of the small table. Eig. 3 shows the top view of the small table. `Eig. 4 shows the under surface of the small table. Eig. 5shows the two posts, shaft, 5o cog-wheel, and Alever attached to the shaft. Eig. 6 shows the tw'o rods.

Similar letters refer to similar parts throughout the several views.

The table A, its standards or posts b b b b, the lposts c e, the feet d, and the small table E constitute the frame-work ofthe machine. On the plate or table A moves the smaller table E backward or forward by means ofthe cog-wheel f and lever Lgin Eig. 5'; and the small table 6o is held in position by the rods in Eig. 6, which pass through the grooves h in Fig. 3 into the standards b b b b, and are fastened by nuts on the end of each rod;and on the outer edge ofthe small table, Fig. 3, is a-straight. cog, z', 65 in which fits the cog-wheel f.

In the posts c c, Fig. 2, the shaft j, Eig. 5, nts.

Letter 7c, Fig. 2, shows the track which fits the groove Z in Fig. 4.

Eig. 2 shows the spaces m n in table.

Fig. 3 shows the spaces m n in the smaller table. 1

I am aware that prior to my invention belt- 75 shifters have been made. I therefore do not claim to be the only inventor of belt-Shifters; but

Vhat I do claim as my invention, and desire to secure by Letters Patent. is

l. The combination, in a belt-shifter, of the two tables A and E, in which are thespaces m n., the track Ic, which fits in the groove Z in table E, and the rods which hold table E in position, all substantially as set forth. 8 5

2. In a belt-shifter, the combination of the cog-wheelf, the straight cog c', and the lever g, substantially as shown, for the purpose specified.
